Abstract
The Night Vision and Electronic Sensors Directorate's (NVESD's) Signatures and Sensors Branch performed a series of experiments to evaluate the feasibility of developing a man portable LIDAR system to perform column content and/or range resolved chemical detection. In order to perform these experiments in an expedient and low cost manner an existing Frequency Agile Laser system was utilized. These experiments were conducted in three phases: (1) full system characterization, (2) chemical cell tests, and (3) simulated stack plume tests. The system characterization was used as a baseline for system performance. Once the system was fully characterized, a series of chemical cell experiments were conducted. The cell test determined to basic feasibility of column content chemical detection and quantification using LIDAR technology. Following a series of successful chemical cell experiment, the stack tests provided a more extensive and realistic way of evaluating column content mode LIDAR capabilities as well as the ability to evaluate the feasibility of performing range resolved chemical detection. Four chemicals were used for the cell and stack experiments. The chemicals were chosen based on real chemical stack exhaust of production plant processes. This paper provides an overview of the LIDAR experiments performed, preliminary data results and analysis, and future efforts planned in support of this project.
